Be it kninvn that l, Cnaanss W. Km'rnolv,

a citizenof the United Stat/25,11 resident of Macomb,jn ,the fmnnt of McDonough and State of Illinois, have invented new and use ful Improvements in Split Insulators, of which t e following is a specification. M invention relates: to improvements in msn ators andprincipally to these'devices which areofthe splittype, that is, which are made andfsold init- 0 parts for convenience in attaching the wire tiereto. r i

The principal object of this invention is the provision of a split insulator in which the parts aremounted on the securing means and prevented from complete separation, provision being made, however. for suliicient movement to enable the wire to;be applied thereto.

A further object of this invention is the provision of a split insulator having the securing means passing therethrough and having a stop or abutment member thereon limiting the movement of the sections of the insulator relative to each other on the' securin means. thereby permitting the application of the wire therebetween', but preventing' the se aration of the sections from each other an from the securing means.

Another object of this invention is the rovision of a split insulator having securmg means therethron h, the parts being movable relative to 930% other siifliciently to permit the application of a wire therebe tween and mmplementary means on he 'partsto cause their to remain in I P all gnment with each other.

l nother object is the provision of a split insulator having the two parts mounted on the securing means and prevented from separation therefrom, but )ermitted to have movement relative to eaci other, so as to permit the application of the wire therebetween, one of the parts having a socket or recess and the other art having a projection or extension fitting in said socket or recess so as to hold the parts in their proper position relative to each other in application.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the combination. construction and arrangement of parts hereinafter described and then sou ht to be defined in the appended claims, re erimam flail February 4, 1916. Serial 110.7641;

ence being had to the accompanyin drawmgs forming a part hereof, and whith shows merely for the purpose of illustrative disclosure, a preferred embodiment of my invention, it being understood that various changes may he made in practice within the scope of the claims without digressing from my inventive idea.

In the drawings, v

Figure 1 represents a side elevation of a device constructed according to my invention, the parts of the insulator being shown separated sufliciently to permit the application of a wire therebetween:

Figure 2 is a vertical longitudinal cross section showing the wire in position, and also indicating in dotted lines, the extent of the movement permitted'between the two sections. whereby the wire may be moved into position in the wire receiving groove;

Figure 3 is agbottom plan view of the top or cap section or part of the insulator;

Figure -l is a top plan view of the bottom part or section of the insulator.

Figure 5 is a perspective view of the underside of the top or cap section part of the insulator.

Split or twwpart insulators are now in eneral and extensive use and are preferred because the wires may be clamped and held ,theiebetween without the necessity of using tie wires. As at present made. they are sub- ;zect to the objection of being inconvenient n application for the reason that in installing them. the base must be placed against the surface, the wire. in the groove the base and then the cap must be sem lected and placed in proper position over the wire in the base and while these parts are being held in position. the installer must select the nail, screw or other securing means, place it in the hole through the sections of the insulator and drive the same with his hammer, screw driver or other tool. It is obviously seen that this consumes considerable tinie and makes the ap lication of the split insulators a rather comp icated pro- 'cedure, particularly in view of the fact,

that the larger part of the installing is done in places inconvenient for access, and in which the installer must assume a very cramped and tiresome position.

By the use of my invention, 1 obviate these objections to a large extent and provide a device having all the advantages of inc yward -what taliomd I also provide the 1 provide in the the s lit insulator, llicl ma be-appl mum e'fliclency. ferring'now and at the same time one ied readily and with naaxito the drawing, top or cap section of. the or base sec u h"havmg" ed rtion 10'. at onQ endEnH-LeiIIg provided with Btopor ahntment of some sort below the botto arts of the 4 the movement of a re -ways 516, tune, prevent an e the two sections 0m V accidental removal f -om the In order to providemeane to two sections orfparlz' of the insulator in proper' osition relative toeaclr other, I

What I claim is 1. A two menta ssemb e latorhaving com lewire ways w on 'd insuecess adapted to maintain the complementary grooves in alignment and being of sufiicient ength to permit relative movement of the two parts to allow a wire to be introduced into and removed from the said grooves without the lug from the re cess, and seeurin means passin through the two pin-Ls of t e insulator an provided with mean- 'for preventing complete separation of the said parts. but rmitting sufficient relative movement of t e said parts of the insulator to enable a wire to be placed in and removed from the said ooves.

2. A two'part insulatofhavlng c'om lemen assemb provided with a tapering oblong recess an the other part being provided with a taperlug oblong stud extenlling into the recess an being of sulficient length to permit relativenibvement of the two sections to enable a wire to be placed in and removed from the said grooves without fdisengaging the stud from the recess, whereby the stud is adapted to maintain the grooves in alignment when the parts of the insulator are either contiguous or separated, and lsecurin means assi through the two parts 0 the insu ator an rovided with means for preventing comp ete separation offthe two parts from each other and from the securing means but permitting sufiicient relative movement of the two parts to placeza wire in and remove the same from the said grooves. 3. A two part insulator having complementary grooves forming wire receivi ways, one of the pa being provided wit an oblong recess ha ing inclined side and end walls and the other part having'a substantiall oblon' stud extending into the recos an provi ed with inclined side'and end faces, said stud being of sufiicient length to' permit relative movement of the said parts to permit a wire to be placed in andremoved from the grooves without disengaging the stud the recess, whereby ves forming wire ways w en ei e part of -t e insulator bein the stud and the recess are adapted to maintain the said rooves in alignment in either position of tie said parts, and securihg means passing through the two parts of -the insulator and provided with means for'pre ventin the complete separation of the said arts m each other and from the securmg means but permittin ment of the two parts to p ace a wire in and remove the same from said grooves,

4. An-insulator formed of sections having bores therethrough, fastening means loosely inserted through the bores, and re taining means carried by and frictionally engagl the fastening means and movable on the atter by engagement therewith of the surface against which the insulator is applied, the retainin means holding the sec hens in loose association on the fastening means and also holdin all the parts of'the insulator in proper re a-tion to each other prior to the application of the insulator.

5. An insulator formed of sections, a fastoning device loosely inserted through and normally holding the sections in associated suilicient inoverelation, the fastening device having a smooth surface construction, and retention means adjustably and frictionally held on said fasteni .device and operating to primarily hold a l the parts of the insulator intact on the fastening device prior to the application of the insulator, the retention means being shifted on the smooth surface of 'the fastening device by engagement there'- of with the surface against which the insulater is applied.
